We are pleased to introduce our latest product within the Humphrey ProControl family, the PCD proportional valve driver. The PCD produces the appropriate current control, either constant current or PWM, to effectively drive any ProControl proportional valve upon receiving signal from a variety of data acquisition sources (ie PLCs, IoT, closed loop sensors, etc).

Ideally suited for product development, laboratories and production environments, the PCD is flexible and user friendly. The PCD features an LCD screen, scroll wheel and pushbutton parameter setting, and tool-less connectivity making set-up fast and easy. Pre-programming includes default settings for all Humphrey ProControl valves and a custom setting for unique application settings. Each PCD is shipped with installation instructions. Unlike competitive proportional valve drivers, the PCD is 100% programmable with fine setting control, no pots or switches to set, and capable of use with any proportional valve specified 1 amp or less with the “custom” setting. It accepts a variety of control signals, namely 0-5v, 0-10v or 4-20mA. Included is short circuit and reverse polarity protection.

New from Humphrey, the iDP Series of inert Diaphragm Poppet valves contain features ideal for hazardous liquid applications. iDP valves are constructed with material suitable for bodily fluids, aggressive chemicals & cleaning fluids and elevated liquid temperatures. The engineered diaphragm feature isolates the liquid media from the solenoid element ensuring long life and sustained performance.

Humphrey iDP valves are INERT to these hazardous conditions, unaffected by hostile liquids and gases, and elevated temperatures.

The small, two-way, 300 Series iDP is comprised of a PEEK body material, and either Viton®GF or EPDM diaphragm, configured into an inline and manifold mount.

The high flow, two way, 350 Series iDP is comprised of either Radel® or Ultem® body material, and Viton®GF or EPDM diaphragm.

The PC30 has exceptional maximum flow, 300LPM at 5.8 watts, and in a compact, 1/8 PIPE, 2-port, valve body. The smaller PC10 valve is a 10-32 threaded, 2-port proportional valve capable of 0-65 LPM flow at 5.8 watt maximum power consumption. The miniature PC3 rounds out the offering at 24 LPM flow at 2.3 maximum power consumption. All are available as inline or manifold mount configurations, with control voltage options of 0-10V or 0-20V, and option picks for maximum pressure ratings and orifice sizes to best suit your application and flow requirements.

All ProControl Proportional Valves are ideal for many types of compressible media including vacuum. With their selectable or dynamic control of media flow, they can be applied to a multitude of market segments such as medical and analytical, testing and instrumentation, as well as factory and process automation. All of the products in the ProControl series are RoHS and REACH compliant.
